This species occurs in the highlands of central Chiapas, Mexico, south-west to the Sierra de los Cuchumatanes, Guatemala. In Guatemala, it occurs on the central Plateaus and in the south-east (1,450-2,340m asl). It probably occurs more widely than current records suggest.
Habitat and Ecology
It occurs in pine-oak and pine-fir forests and high grasslands. Breeding takes place in temporary ponds.
It is uncommon in Guatemala and has not been seen since 1995. Extensive recent surveys in the last few years indicate that this species is nearing extirpation in this country. It is still abundant in Chiapas.
Loss of habitat due to agriculture, logging, and human settlement is the major threat.
It occurs in the Parque Nacional Lagunas de Montebello in Mexico, but is not recorded from any protected areas in Guatemala.
Red List Status
Listed as Vulnerable because its Extent of Occurrence is less than 20,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in Mexico and Guatemala.
